If USCIS issued a notice and you have not received it or it does not appear in your online account, then you may submit an inquiry. NOTE: You should receive a receipt notice within 30 days after filing an application or petition at a Service Center or Lockbox.
Mark the envelope and the cover letter with the type of submission. For example, Original Submission, Application to Register Permanent Residence or Adjust Status (Form I-485). Mark the envelope and the cover letter with the form number.
Submit a secure message through your USCIS online account. Submit an inquiry through the Ask Emma chat feature. Call the USCIS Contact Center at 1-800-375-5283. See our USCIS Contact Center Tip Sheet on how to best reach out to the USCIS Contact Center.
Your letter should be addressed to the USCIS office that is responsible for your case. You can find the address on the USCIS website or by contacting the USCIS national customer service center. You should also include a clear and professional salutation, such as “Dear USCIS Officer” or “To Whom It May Concern.”
Generally, I don't want people corresponding with USCIS, unless they've been asked to do so. It's generally not a good idea to just out of the blue, write USCIS a letter. So our advice generally is to not send USCIS a letter.
Start with an introduction that clearly states your purpose and why you're writing the letter. In the middle section, provide a detailed explanation of your request or concern. Use supporting evidence to make your case as strong as possible. Finally, end your letter with a polite but firm request for action.
You may send your forms through USPS, FedEx, DHL, or UPS. We encourage you to save a copy of your payment, along with any tracking number provided by the courier, for your records and so you can verify the status of its delivery.
It will take approximately 30 days from the date the card is received for USCIS to process your request and, if we determine it was due to USCIS error, to issue you a new card.
